I dont think the bird in question is also cinnamon, his face mask is black, not cinnamon. Its only the lighting in the pictures that make us think/see his is lighter.
Also the black can vary from bird to bird.
I love my budgies
Thank you FaeryBee for the signature
As said already, he is definitely a Grey Green. The markings look too dark in some of the photos for a Cinnamon but his feathers have that soft smooth look of a Cinnamon so I wouldn't be surprised if he was.
